This is the technology of double rotor and radial flow

deep drive It is a German company based in Munich that was created ten years ago from the work of students at the University of Munich. It managed to raise 15 million euros in its initial investment round. It has also received financial support from UVC Partners, Bayern Kapital and… Peter Mertens, former member of the management board responsible for Audi development. Your product is a revolutionary technology that BMW and Continental are also interested in.

In 2021, DeepDrive showed a The prototype of his engine is in the wheel at the Frankfurt Motor Show. This patented technology allows more torque and power to be achieved compared to conventional torque, which translates into 20% greater autonomy in electric vehicles that integrate it or a 20% smaller battery.

The new DeepDrive

Based on this architecture, The new DeepDrive It will be available in two variants. he Deep Drive CSD 450 Provides power output from 230 kW and torque 430 Nm. It is suitable as a prime mover electric car normali.e. with front, rear or all-wheel drive and up to C-segment size.

On the other hand it is Deep Drive CSD 700 Provides power output from 350 kW and even 5400 Nm output torque. Due to its specifications, it is positioned as the flagship unit for luxury cars in the D-segment, as well as all-wheel drive configurations.

According to DeepDrive, both options offer high efficiency (more than 96% and wide operating range. The company guarantees that it contributes to “an increase in autonomy of up to 20% compared to existing solutions” which is why many manufacturers have already expressed interest in the new unit. The first series of deliveries is scheduled for 2027.

Dual rotor technology

The double radial flow electric machine increases power density and torque with minimal noise emission and a simple and efficient cooling system. To do this, use a Revolutionary winding concept Which he calls “distributed tape” and through which he achieves a filling factor for the holes between the threads by more than 80%, which in turn is easy to manufacture.

It integrates an inverter with ultra-efficient silicon carbide (SiC) technology, with an innovative and patented topology, which uses MOSFET or semiconductor transistors that regulate the output voltage to improve and reduce losses.

This technology, patented by DeepDrive, Ensures profitability and sustainability This is thanks to the use of 50% less magnetic materials, i.e. permanent magnets made of rare earths, and 80% less iron. The result is an engine with an Nm cost of 30% less than conventional motors.

Alexander RosenThe DeepDrive co-founder and systems design engineer explains that high purchase and operating costs remain a barrier for potential electric vehicle buyers. “Our drive unit breaks this trend by offering a solution that not only reduces component costs, but also significantly increases efficiency, which in turn has a strong impact on battery costs and, ultimately, guarantees greater vehicle autonomy for customers in daily use.”

Dual rotor radial flow technology eliminates the previous weaknesses. “Technical hurdles can be resolved. The advantages of this drive technology are so great that they will prove themselves as soon as they become competitive in terms of price. I am convinced of that,” adds Rosen. DeepDrive Power electronics included They can be installed in production vehicles for their location It is placed centrally as it is in the hub of a wheel.
